Question

【題目】 Many people know that rubbish is a big problem on planet Earth. What many people don't know is that junk has become a problem in outer space too.

According to BBC News, there are more than 22, 000 pieces of space junk floating around the earth. And these are just the things that we can see from the surface of the earth by telescopes. There are also millions of smaller pieces of junk that we can't see.

Objects, like bits of old space rockets or satellites(衛(wèi)星), move around the planet at very high speeds fast that even a very small piece can break important satellites or become dangerous to astronauts. If the tiniest piece of junk crashed into a spaceship, it could damage the vehicle（軌道）.

To make things worse, when two objects in space crash, they break into many smaller pieces. For example, when a U.S. satellite hit an old Russian rocket in 2009, it broke into more than 2,000 pieces, increasing the amount of space junk.

To reduce additional space junk, countries have agreed that all new space tools can only stay in space for 25 years at most. Each tool must be built to fall safely into the earth's atmosphere after that time. In the upper parts of the atmosphere, it will burn up.

Many scientists also suggest different ways to clean up space junk. In England scientists are testing a metal net that can be fired into space junk. The net catches the junk and then pulls it into the earth's atmosphere to burn up. The Germans are building robots that can collect pieces of space junk and bring them back to Earth to be safely destroyed.

The problem is becoming more challenging because we're sending more objects into space to help people use their mobile phones and computers,” says Marco Castronuovo, an Italian space Researcher.

“The time to act is now. The longer we leave the problem, the bigger it will become,” he says.

【解析】

本文是說明文，主要講述了垃圾不僅是地球上，而且也是太空里的一大問題，對人類生存環(huán)境造成極大的影響，許多科學(xué)家也提出了清理太空垃圾的不同方法。

【1】詞義猜測題。根據(jù)第2大段“According to BBC News, there are more than 22, 000 pieces of space junk floating around the earth.”在地球周圍有22000多塊太空垃圾漂浮著可知，代指垃圾碎片。故選C。

【2】細(xì)節(jié)理解題。根據(jù)第3大段“even a very small piece can break important satellites or become dangerous to astronauts. If the tiniest piece of junk crashed into a spaceship, it could damage the vehicle（軌道）.”即使是非常小的一塊也會損壞重要的衛(wèi)星或?qū)τ詈絾T造成危險(xiǎn)。如果最小的塊垃圾撞上一艘宇宙飛船，它可能損害軌道�？芍�它可能會撞上太空里的其他東西，這會造成傷亡或者損害。故選C。

【3】細(xì)節(jié)理解題。根據(jù)第5大段“To reduce additional space junk, countries have agreed that all new space tools can only stay in space for 25 years at most. Each tool must be built to fall safely into the earth's atmosphere after that time”為了減少太空額外垃圾，國家同意所有的新型太空工具最多能在太空中待25年.每一個(gè)工具都必須在那個(gè)時(shí)間之后安全降落到地球的大氣層中�？芍�，為了讓太空工具不會成為太空垃圾。。故選B。

【4】細(xì)節(jié)理解題。根據(jù)第6大段“The Germans are building robots that can collect pieces of space junk and bring them back to Earth to be safely destroyed.”德國人正在制造能夠收集太空垃圾碎片并將其帶回地球安全銷毀的機(jī)器人�？芍�，是用機(jī)器人收集垃圾碎片。故選A。

【5】推測判斷題。根據(jù)第1大段“Many people know that rubbish is a big problem on planet Earth. What many people don't know is that junk has become a problem in outer space too.”許多人知道垃圾是地球上的一個(gè)大問題。許多人不知道的是，太空垃圾也成為了太空中的一個(gè)問題。可知，本文主要講述的是太空垃圾，環(huán)境的問題，所以可能會出現(xiàn)在報(bào)紙上的環(huán)境板塊。故選A。
